I have sent BTC to coinbase via my Bitcoin QT but i sent the BTC with no miner fees, there after my transaction has been rejected and pruned ,, I read in the comment that if the transaction is rejected the the funds will go back to the wallet address it was sent from, usually within minutes sometimes longer, I have the same problem BUT i have been waiting about 7 days and the block chain is saying "Transaction rejected by our node. Reason: Transaction was previously accepted but has been pruned from our database" But my Bitcoin QT have no refund of BItcoin and my Bitcoin QT balance is still 0.00, does this mean my BTC IS LOST for ever?
also my bitcoin Qt is fully synced

please help
